(a) Atoms are very small compared to objects on the macroscopic scale. The radius of a aluminum atom is 143
pm. What is this value in meters and in centimeters?
m
cm
(b) The mass of a single aluminum atom is 4.48×10-23 g. Suppose enough Al atoms were lined up like beads on
a string to span a distance of 37.7 cm (15 inches). How many atoms would be required?
atoms
What mass in grams of Al would be used?
g
Could you weigh out this amount of aluminum using a typical laboratory balance?
(c) Taking the density of aluminum metal to be 2.70 g/cm³, calculate the mass of metal needed to form a piece of
Al wire with the same length as the distance in b, but with a diameter of 1.00 mm. Hint: The volume of a cylinder is
n times its radius squared times its height. (V = n r² h)
